Modeling and sensitivity analysis of HBV epidemic model with convex incidence rate

open access: yesResults in Physics, 2021
In this article, we study the qualitative analysis of the Hepatitis B epidemic model with convex incidence rate. First, we formulate the model without control and study local and global stability.

Dynamic model of COVID-19 and citizens reaction using fractional derivative

open access: yesAlexandria Engineering Journal, 2021
This paper presents dynamic model of COVID-19 and citizens reaction from a fraction of the population in Nigeria using fractional derivative. We consider the reported cases from February to June 2020 using fractional derivative. The Stability analysis of

Global dynamics, Neimark-Sacker bifurcation and hybrid control in a Leslie’s prey-predator model

open access: yesAlexandria Engineering Journal, 2022
In the present study, we explore the topological classifications at fixed points, global dynamics, Neimark-Sacker bifurcation and hybrid control in the two-dimensional discrete-time Leslie’s prey-predator model.

Complex dynamics of a nonlinear discrete predator-prey system with Allee effect

open access: yesOpen Mathematics
The transition between strong and weak Allee effects in prey provides a simple regime shift in ecology. In this article, we study a discrete predator-prey system with Holling type II functional response and Allee effect. First, the number of fixed points
